Ahh a painful thread
There is a piece of production art I have been looking at for over a year, but the person wants to only trade it for Original art. I was hoping to purchase it as it was a rejected page but still is one of my favorite character and would go well with the OA and even the Color Pages from the book I have.
I think it is fantastic when a collector gets the Original Comic, the OA from that comic, color page and if there is one a pre-production page.
It shows dedication to the art and artists, and a willingness to preserve something that could have easily been lost.
Good Luck everyone in this years collecting
